Teaching is stressful, very stressful. Research by the Teachers Assurance found that 76% of teachers believe the pressure of their work was having a negative impact on their health. Similar percentages were reported in The Association of Teachers and Lecturers 2012 survey, with 73% reporting that this pressure was negatively affecting their wellbeing, and many believing that their confidence in their ability and their relationship with their partners were suffering as a result. So why are teachers feeling the pressure? Take your pick: demands to be high up the league table; reduced staffing; financial worries. This is only set to increase with the introduction of performance related pay.
